Lorenzo is not fit to race and he is placing not just himself but others at risk because when he ran across the gravel and came bounding back on to the track he had no way of knowing if another rider was coming and he was not in control of the bike. You need your legs and your feet hard on pegs. But this is not a decision he should be making. I remember racing with a badly broken collarbone and when the bike crossed up I just fell off of it. I also encouraged my son to race a half mile Texas Dirt Track when he had a badly injured shoulder. Dean Miller told it to me straight...if he crashes he could seriously hurt himself. But he needed points. The medical staff is being irresponsible.
